I've this pc for 2 years now and play the same games ever. Recently my pc turns of the image midgame and the fans of the gpu start going a lot faster. I've removed it and cleaned from the dust but the problem persists. The MSI afterburner is installed as well and the tmp is no more than 50º. I can still hear the sound of the game runing.
The gpu is an AMD Radeon R9 390 series. I've no idea of what to do next since the problem came from nowhere and noreason.
